Check Digit Verification of cas no
The CAS Registry Mumber 1307865-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,7,8,6 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1307865-21:
(9*1)+(8*3)+(7*0)+(6*7)+(5*8)+(4*6)+(3*5)+(2*2)+(1*1)=159
159 % 10 = 9
So 1307865-21-9 is a valid CAS Registry Number.
