1007216-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1007216-51-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,7,2,1 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1007216-51:
(9*1)+(8*0)+(7*0)+(6*7)+(5*2)+(4*1)+(3*6)+(2*5)+(1*1)=94
94 % 10 = 4
So 1007216-51-4 is a valid CAS Registry Number.
