Check Digit Verification of cas no
The CAS Registry Mumber 477781-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,7,8 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 477781-69:
(8*4)+(7*7)+(6*7)+(5*7)+(4*8)+(3*1)+(2*6)+(1*9)=214
214 % 10 = 4
So 477781-69-4 is a valid CAS Registry Number.
