Check Digit Verification of cas no
The CAS Registry Mumber 1312023-29-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,0,2 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1312023-29:
(9*1)+(8*3)+(7*1)+(6*2)+(5*0)+(4*2)+(3*3)+(2*2)+(1*9)=82
82 % 10 = 2
So 1312023-29-2 is a valid CAS Registry Number.
