Check Digit Verification of cas no
The CAS Registry Mumber 217651-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,6,5 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 217651-53:
(8*2)+(7*1)+(6*7)+(5*6)+(4*5)+(3*1)+(2*5)+(1*3)=131
131 % 10 = 1
So 217651-53-1 is a valid CAS Registry Number.
