Check Digit Verification of cas no
The CAS Registry Mumber 52010-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,1 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52010-22:
(7*5)+(6*2)+(5*0)+(4*1)+(3*0)+(2*2)+(1*2)=57
57 % 10 = 7
So 52010-22-7 is a valid CAS Registry Number.
