1220993-82-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1220993-82-7 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 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1220993-82:
(9*1)+(8*2)+(7*2)+(6*0)+(5*9)+(4*9)+(3*3)+(2*8)+(1*2)=147
147 % 10 = 7
So 1220993-82-7 is a valid CAS Registry Number.
