Check Digit Verification of cas no
The CAS Registry Mumber 10127-27-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,2 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 10127-27:
(7*1)+(6*0)+(5*1)+(4*2)+(3*7)+(2*2)+(1*7)=52
52 % 10 = 2
So 10127-27-2 is a valid CAS Registry Number.
