Check Digit Verification of cas no
The CAS Registry Mumber 1624-02-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1624-02:
(6*1)+(5*6)+(4*2)+(3*4)+(2*0)+(1*2)=58
58 % 10 = 8
So 1624-02-8 is a valid CAS Registry Number.
