Check Digit Verification of cas no
The CAS Registry Mumber 277335-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,7,3,3 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 277335-21:
(8*2)+(7*7)+(6*7)+(5*3)+(4*3)+(3*5)+(2*2)+(1*1)=154
154 % 10 = 4
So 277335-21-4 is a valid CAS Registry Number.
