Check Digit Verification of cas no
The CAS Registry Mumber 4253-22-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4253-22:
(6*4)+(5*2)+(4*5)+(3*3)+(2*2)+(1*2)=69
69 % 10 = 9
So 4253-22-9 is a valid CAS Registry Number.
