Check Digit Verification of cas no
The CAS Registry Mumber 185107-64-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,1,0 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 185107-64:
(8*1)+(7*8)+(6*5)+(5*1)+(4*0)+(3*7)+(2*6)+(1*4)=136
136 % 10 = 6
So 185107-64-6 is a valid CAS Registry Number.
