Check Digit Verification of cas no
The CAS Registry Mumber 132407-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,0 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132407-92:
(8*1)+(7*3)+(6*2)+(5*4)+(4*0)+(3*7)+(2*9)+(1*2)=102
102 % 10 = 2
So 132407-92-2 is a valid CAS Registry Number.
