Check Digit Verification of cas no
The CAS Registry Mumber 136780-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,8 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136780-31:
(8*1)+(7*3)+(6*6)+(5*7)+(4*8)+(3*0)+(2*3)+(1*1)=139
139 % 10 = 9
So 136780-31-9 is a valid CAS Registry Number.
