Check Digit Verification of cas no
The CAS Registry Mumber 2829-42-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,2 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2829-42:
(6*2)+(5*8)+(4*2)+(3*9)+(2*4)+(1*2)=97
97 % 10 = 7
So 2829-42-7 is a valid CAS Registry Number.
