Check Digit Verification of cas no
The CAS Registry Mumber 78377-63-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,7 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78377-63:
(7*7)+(6*8)+(5*3)+(4*7)+(3*7)+(2*6)+(1*3)=176
176 % 10 = 6
So 78377-63-6 is a valid CAS Registry Number.
