Check Digit Verification of cas no
The CAS Registry Mumber 22052-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,5 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22052-03:
(7*2)+(6*2)+(5*0)+(4*5)+(3*2)+(2*0)+(1*3)=55
55 % 10 = 5
So 22052-03-5 is a valid CAS Registry Number.
