183722-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183722-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,7,2 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 183722-50:
(8*1)+(7*8)+(6*3)+(5*7)+(4*2)+(3*2)+(2*5)+(1*0)=141
141 % 10 = 1
So 183722-50-1 is a valid CAS Registry Number.
