Check Digit Verification of cas no
The CAS Registry Mumber 3690-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,9 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3690-50:
(6*3)+(5*6)+(4*9)+(3*0)+(2*5)+(1*0)=94
94 % 10 = 4
So 3690-50-4 is a valid CAS Registry Number.
