Check Digit Verification of cas no
The CAS Registry Mumber 1616487-09-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,4,8 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1616487-09:
(9*1)+(8*6)+(7*1)+(6*6)+(5*4)+(4*8)+(3*7)+(2*0)+(1*9)=182
182 % 10 = 2
So 1616487-09-2 is a valid CAS Registry Number.
