Check Digit Verification of cas no
The CAS Registry Mumber 151095-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,0,9 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 151095-12:
(8*1)+(7*5)+(6*1)+(5*0)+(4*9)+(3*5)+(2*1)+(1*2)=104
104 % 10 = 4
