Check Digit Verification of cas no
The CAS Registry Mumber 956469-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,6,4,6 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 956469-18:
(8*9)+(7*5)+(6*6)+(5*4)+(4*6)+(3*9)+(2*1)+(1*8)=224
224 % 10 = 4
So 956469-18-4 is a valid CAS Registry Number.
