Check Digit Verification of cas no
The CAS Registry Mumber 1327-10-2 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 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1327-10:
(6*1)+(5*3)+(4*2)+(3*7)+(2*1)+(1*0)=52
52 % 10 = 2
So 1327-10-2 is a valid CAS Registry Number.
