Check Digit Verification of cas no
The CAS Registry Mumber 117836-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,3 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117836-05:
(8*1)+(7*1)+(6*7)+(5*8)+(4*3)+(3*6)+(2*0)+(1*5)=132
132 % 10 = 2
So 117836-05-2 is a valid CAS Registry Number.
