Check Digit Verification of cas no
The CAS Registry Mumber 136937-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,3 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136937-06:
(8*1)+(7*3)+(6*6)+(5*9)+(4*3)+(3*7)+(2*0)+(1*6)=149
149 % 10 = 9
So 136937-06-9 is a valid CAS Registry Number.
