917508-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917508-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,5,0 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 917508-99:
(8*9)+(7*1)+(6*7)+(5*5)+(4*0)+(3*8)+(2*9)+(1*9)=197
197 % 10 = 7
So 917508-99-7 is a valid CAS Registry Number.
