1013643-62-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1013643-62-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,3,6,4 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1013643-62:
(9*1)+(8*0)+(7*1)+(6*3)+(5*6)+(4*4)+(3*3)+(2*6)+(1*2)=103
103 % 10 = 3
So 1013643-62-3 is a valid CAS Registry Number.
