Check Digit Verification of cas no
The CAS Registry Mumber 133658-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,5 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133658-23:
(8*1)+(7*3)+(6*3)+(5*6)+(4*5)+(3*8)+(2*2)+(1*3)=128
128 % 10 = 8
So 133658-23-8 is a valid CAS Registry Number.
