117953-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117953-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,5 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117953-08:
(8*1)+(7*1)+(6*7)+(5*9)+(4*5)+(3*3)+(2*0)+(1*8)=139
139 % 10 = 9
