Check Digit Verification of cas no
The CAS Registry Mumber 21907-50-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21907-50:
(7*2)+(6*1)+(5*9)+(4*0)+(3*7)+(2*5)+(1*0)=96
96 % 10 = 6
So 21907-50-6 is a valid CAS Registry Number.
