917908-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917908-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,9,0 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 917908-21:
(8*9)+(7*1)+(6*7)+(5*9)+(4*0)+(3*8)+(2*2)+(1*1)=195
195 % 10 = 5
So 917908-21-5 is a valid CAS Registry Number.
