1021297-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1021297-93-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,2,9 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1021297-93:
(9*1)+(8*0)+(7*2)+(6*1)+(5*2)+(4*9)+(3*7)+(2*9)+(1*3)=117
117 % 10 = 7
So 1021297-93-7 is a valid CAS Registry Number.
