Check Digit Verification of cas no
The CAS Registry Mumber 71989-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,8 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71989-32:
(7*7)+(6*1)+(5*9)+(4*8)+(3*9)+(2*3)+(1*2)=167
167 % 10 = 7
So 71989-32-7 is a valid CAS Registry Number.
