Check Digit Verification of cas no
The CAS Registry Mumber 1309460-30-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,4,6 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1309460-30:
(9*1)+(8*3)+(7*0)+(6*9)+(5*4)+(4*6)+(3*0)+(2*3)+(1*0)=137
137 % 10 = 7
So 1309460-30-7 is a valid CAS Registry Number.
