1138700-25-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1138700-25-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,7,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1138700-25:
(9*1)+(8*1)+(7*3)+(6*8)+(5*7)+(4*0)+(3*0)+(2*2)+(1*5)=130
130 % 10 = 0
So 1138700-25-0 is a valid CAS Registry Number.
