3991-76-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3991-76-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3991-76:
(6*3)+(5*9)+(4*9)+(3*1)+(2*7)+(1*6)=122
122 % 10 = 2
So 3991-76-2 is a valid CAS Registry Number.
