142672-67-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142672-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,7 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142672-67:
(8*1)+(7*4)+(6*2)+(5*6)+(4*7)+(3*2)+(2*6)+(1*7)=131
131 % 10 = 1
So 142672-67-1 is a valid CAS Registry Number.
