3-4Check Digit Verification of cas no
The CAS Registry Mumber 1326-51-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.Calculate Digit Verification of CAS Registry Number 1326-51:
(6*1)+(5*3)+(4*2)+(3*6)+(2*5)+(1*1)=58
58 % 10 = 8
So 1326-51-8 is a valid CAS Registry Number.
