Check Digit Verification of cas no
The CAS Registry Mumber 136497-67-1 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 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136497-67:
(8*1)+(7*3)+(6*6)+(5*4)+(4*9)+(3*7)+(2*6)+(1*7)=161
161 % 10 = 1
So 136497-67-1 is a valid CAS Registry Number.
