Check Digit Verification of cas no
The CAS Registry Mumber 12671-74-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,6,7 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12671-74:
(7*1)+(6*2)+(5*6)+(4*7)+(3*1)+(2*7)+(1*4)=98
98 % 10 = 8
So 12671-74-8 is a valid CAS Registry Number.
