Check Digit Verification of cas no
The CAS Registry Mumber 1029612-18-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,9,6,1 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1029612-18:
(9*1)+(8*0)+(7*2)+(6*9)+(5*6)+(4*1)+(3*2)+(2*1)+(1*8)=127
127 % 10 = 7
So 1029612-18-7 is a valid CAS Registry Number.
