Check Digit Verification of cas no
The CAS Registry Mumber 68281-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 68281-65:
(7*6)+(6*8)+(5*2)+(4*8)+(3*1)+(2*6)+(1*5)=152
152 % 10 = 2
So 68281-65-2 is a valid CAS Registry Number.
