Check Digit Verification of cas no
The CAS Registry Mumber 141988-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141988-20:
(8*1)+(7*4)+(6*1)+(5*9)+(4*8)+(3*8)+(2*2)+(1*0)=147
