139662-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139662-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,6 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139662-76:
(8*1)+(7*3)+(6*9)+(5*6)+(4*6)+(3*2)+(2*7)+(1*6)=163
163 % 10 = 3
So 139662-76-3 is a valid CAS Registry Number.
