Check Digit Verification of cas no
The CAS Registry Mumber 17527-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,2 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17527-17:
(7*1)+(6*7)+(5*5)+(4*2)+(3*7)+(2*1)+(1*7)=112
112 % 10 = 2
So 17527-17-2 is a valid CAS Registry Number.
