Check Digit Verification of cas no
The CAS Registry Mumber 143237-91-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,3 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143237-91:
(8*1)+(7*4)+(6*3)+(5*2)+(4*3)+(3*7)+(2*9)+(1*1)=116
116 % 10 = 6
So 143237-91-6 is a valid CAS Registry Number.
