Check Digit Verification of cas no
The CAS Registry Mumber 3624-68-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,2 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3624-68:
(6*3)+(5*6)+(4*2)+(3*4)+(2*6)+(1*8)=88
88 % 10 = 8
So 3624-68-8 is a valid CAS Registry Number.
