83781-72-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83781-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,8 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83781-72:
(7*8)+(6*3)+(5*7)+(4*8)+(3*1)+(2*7)+(1*2)=160
160 % 10 = 0
So 83781-72-0 is a valid CAS Registry Number.
