158983-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158983-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,9,8 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 158983-12:
(8*1)+(7*5)+(6*8)+(5*9)+(4*8)+(3*3)+(2*1)+(1*2)=181
181 % 10 = 1
So 158983-12-1 is a valid CAS Registry Number.
