Check Digit Verification of cas no
The CAS Registry Mumber 1609651-90-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,6,5 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1609651-90:
(9*1)+(8*6)+(7*0)+(6*9)+(5*6)+(4*5)+(3*1)+(2*9)+(1*0)=182
182 % 10 = 2
So 1609651-90-2 is a valid CAS Registry Number.
