Check Digit Verification of cas no
The CAS Registry Mumber 159404-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,4,0 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 159404-79:
(8*1)+(7*5)+(6*9)+(5*4)+(4*0)+(3*4)+(2*7)+(1*9)=152
152 % 10 = 2
So 159404-79-2 is a valid CAS Registry Number.
