Check Digit Verification of cas no
The CAS Registry Mumber 32279-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,2,7 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 32279-04:
(7*3)+(6*2)+(5*2)+(4*7)+(3*9)+(2*0)+(1*4)=102
102 % 10 = 2
So 32279-04-2 is a valid CAS Registry Number.
