Check Digit Verification of cas no
The CAS Registry Mumber 128742-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,4 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128742-65:
(8*1)+(7*2)+(6*8)+(5*7)+(4*4)+(3*2)+(2*6)+(1*5)=144
144 % 10 = 4
So 128742-65-4 is a valid CAS Registry Number.
