Check Digit Verification of cas no
The CAS Registry Mumber 213892-95-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,8,9 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 213892-95:
(8*2)+(7*1)+(6*3)+(5*8)+(4*9)+(3*2)+(2*9)+(1*5)=146
146 % 10 = 6
So 213892-95-6 is a valid CAS Registry Number.
