1329-27-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1329-27-7 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 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1329-27:
(6*1)+(5*3)+(4*2)+(3*9)+(2*2)+(1*7)=67
67 % 10 = 7
So 1329-27-7 is a valid CAS Registry Number.
