Check Digit Verification of cas no
The CAS Registry Mumber 7467-27-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,6 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7467-27:
(6*7)+(5*4)+(4*6)+(3*7)+(2*2)+(1*7)=118
118 % 10 = 8
So 7467-27-8 is a valid CAS Registry Number.
