Check Digit Verification of cas no
The CAS Registry Mumber 217657-66-4 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 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 217657-66:
(8*2)+(7*1)+(6*7)+(5*6)+(4*5)+(3*7)+(2*6)+(1*6)=154
154 % 10 = 4
So 217657-66-4 is a valid CAS Registry Number.
