Check Digit Verification of cas no
The CAS Registry Mumber 136498-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,9 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136498-54:
(8*1)+(7*3)+(6*6)+(5*4)+(4*9)+(3*8)+(2*5)+(1*4)=159
159 % 10 = 9
So 136498-54-9 is a valid CAS Registry Number.
