Check Digit Verification of cas no
The CAS Registry Mumber 3688-79-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,8 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3688-79:
(6*3)+(5*6)+(4*8)+(3*8)+(2*7)+(1*9)=127
127 % 10 = 7
So 3688-79-7 is a valid CAS Registry Number.
