1220997-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1220997-93-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,9,9 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1220997-93:
(9*1)+(8*2)+(7*2)+(6*0)+(5*9)+(4*9)+(3*7)+(2*9)+(1*3)=162
162 % 10 = 2
So 1220997-93-2 is a valid CAS Registry Number.
