Check Digit Verification of cas no
The CAS Registry Mumber 102781-35-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,7,8 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 102781-35:
(8*1)+(7*0)+(6*2)+(5*7)+(4*8)+(3*1)+(2*3)+(1*5)=101
101 % 10 = 1
So 102781-35-1 is a valid CAS Registry Number.
