Check Digit Verification of cas no
The CAS Registry Mumber 133560-78-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,6 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133560-78:
(8*1)+(7*3)+(6*3)+(5*5)+(4*6)+(3*0)+(2*7)+(1*8)=118
118 % 10 = 8
So 133560-78-8 is a valid CAS Registry Number.
