917897-66-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917897-66-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,8,9 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 917897-66:
(8*9)+(7*1)+(6*7)+(5*8)+(4*9)+(3*7)+(2*6)+(1*6)=236
236 % 10 = 6
So 917897-66-6 is a valid CAS Registry Number.
