Check Digit Verification of cas no
The CAS Registry Mumber 1307704-50-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,7,7,0 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1307704-50:
(9*1)+(8*3)+(7*0)+(6*7)+(5*7)+(4*0)+(3*4)+(2*5)+(1*0)=132
132 % 10 = 2
So 1307704-50-2 is a valid CAS Registry Number.
