Check Digit Verification of cas no
The CAS Registry Mumber 3737-76-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3737-76:
(6*3)+(5*7)+(4*3)+(3*7)+(2*7)+(1*6)=106
106 % 10 = 6
So 3737-76-6 is a valid CAS Registry Number.
