1630958-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1630958-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,0,9,5 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1630958-22:
(9*1)+(8*6)+(7*3)+(6*0)+(5*9)+(4*5)+(3*8)+(2*2)+(1*2)=173
173 % 10 = 3
So 1630958-22-3 is a valid CAS Registry Number.
