Check Digit Verification of cas no
The CAS Registry Mumber 944838-62-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,8,3 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 944838-62:
(8*9)+(7*4)+(6*4)+(5*8)+(4*3)+(3*8)+(2*6)+(1*2)=214
214 % 10 = 4
So 944838-62-4 is a valid CAS Registry Number.
