Check Digit Verification of cas no
The CAS Registry Mumber 377777-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,7,7,7 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 377777-91:
(8*3)+(7*7)+(6*7)+(5*7)+(4*7)+(3*7)+(2*9)+(1*1)=218
218 % 10 = 8
So 377777-91-8 is a valid CAS Registry Number.
