129083-42-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129083-42-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,8 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129083-42:
(8*1)+(7*2)+(6*9)+(5*0)+(4*8)+(3*3)+(2*4)+(1*2)=127
127 % 10 = 7
So 129083-42-7 is a valid CAS Registry Number.
