1155315-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1155315-21-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,5,3,1 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1155315-21:
(9*1)+(8*1)+(7*5)+(6*5)+(5*3)+(4*1)+(3*5)+(2*2)+(1*1)=121
121 % 10 = 1
So 1155315-21-1 is a valid CAS Registry Number.
