133712-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133712-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,1 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133712-76:
(8*1)+(7*3)+(6*3)+(5*7)+(4*1)+(3*2)+(2*7)+(1*6)=112
112 % 10 = 2
So 133712-76-2 is a valid CAS Registry Number.
