Check Digit Verification of cas no
The CAS Registry Mumber 121695-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,9 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121695-87:
(8*1)+(7*2)+(6*1)+(5*6)+(4*9)+(3*5)+(2*8)+(1*7)=132
132 % 10 = 2
So 121695-87-2 is a valid CAS Registry Number.
