Check Digit Verification of cas no
The CAS Registry Mumber 774492-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,4,4,9 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 774492-91:
(8*7)+(7*7)+(6*4)+(5*4)+(4*9)+(3*2)+(2*9)+(1*1)=210
210 % 10 = 0
So 774492-91-0 is a valid CAS Registry Number.
