NotclassifiedCheck Digit Verification of cas no
The CAS Registry Mumber 141880-36-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,8 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.Calculate Digit Verification of CAS Registry Number 141880-36:
(8*1)+(7*4)+(6*1)+(5*8)+(4*8)+(3*0)+(2*3)+(1*6)=126
126 % 10 = 6
So 141880-36-6 is a valid CAS Registry Number.
