Check Digit Verification of cas no
The CAS Registry Mumber 294885-62-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,4,8,8 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 294885-62:
(8*2)+(7*9)+(6*4)+(5*8)+(4*8)+(3*5)+(2*6)+(1*2)=204
204 % 10 = 4
So 294885-62-4 is a valid CAS Registry Number.
