Check Digit Verification of cas no
The CAS Registry Mumber 13645-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,4 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13645-74:
(7*1)+(6*3)+(5*6)+(4*4)+(3*5)+(2*7)+(1*4)=104
104 % 10 = 4
So 13645-74-4 is a valid CAS Registry Number.
