Check Digit Verification of cas no
The CAS Registry Mumber 39279-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,7 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39279-59:
(7*3)+(6*9)+(5*2)+(4*7)+(3*9)+(2*5)+(1*9)=159
159 % 10 = 9
So 39279-59-9 is a valid CAS Registry Number.
