Check Digit Verification of cas no
The CAS Registry Mumber 1237745-09-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,4 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1237745-09:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*4)+(3*5)+(2*0)+(1*9)=163
163 % 10 = 3
So 1237745-09-3 is a valid CAS Registry Number.
