Check Digit Verification of cas no
The CAS Registry Mumber 7789-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7789-79:
(6*7)+(5*7)+(4*8)+(3*9)+(2*7)+(1*9)=159
159 % 10 = 9
So 7789-79-9 is a valid CAS Registry Number.
