Check Digit Verification of cas no
The CAS Registry Mumber 371978-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,1,9,7 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 371978-05:
(8*3)+(7*7)+(6*1)+(5*9)+(4*7)+(3*8)+(2*0)+(1*5)=181
181 % 10 = 1
So 371978-05-1 is a valid CAS Registry Number.
