Check Digit Verification of cas no
The CAS Registry Mumber 293731-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,7,3 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 293731-50:
(8*2)+(7*9)+(6*3)+(5*7)+(4*3)+(3*1)+(2*5)+(1*0)=157
157 % 10 = 7
So 293731-50-7 is a valid CAS Registry Number.
