Check Digit Verification of cas no
The CAS Registry Mumber 256417-12-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,4,1 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 256417-12:
(8*2)+(7*5)+(6*6)+(5*4)+(4*1)+(3*7)+(2*1)+(1*2)=136
136 % 10 = 6
So 256417-12-6 is a valid CAS Registry Number.
