1217737-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217737-83-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,7,3 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1217737-83:
(9*1)+(8*2)+(7*1)+(6*7)+(5*7)+(4*3)+(3*7)+(2*8)+(1*3)=161
161 % 10 = 1
So 1217737-83-1 is a valid CAS Registry Number.
