Check Digit Verification of cas no
The CAS Registry Mumber 219702-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,0 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 219702-41:
(8*2)+(7*1)+(6*9)+(5*7)+(4*0)+(3*2)+(2*4)+(1*1)=127
127 % 10 = 7
So 219702-41-7 is a valid CAS Registry Number.
