176504-18-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176504-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,5,0 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 176504-18:
(8*1)+(7*7)+(6*6)+(5*5)+(4*0)+(3*4)+(2*1)+(1*8)=140
140 % 10 = 0
So 176504-18-0 is a valid CAS Registry Number.

A convenient procedure for the reduction of S-(+)-silyl serine methyl ester to chiral serinol derivatives
Novachek, Katherine A.,Meyers
, p. 1743 - 1746 (1996)
The reduction of S-(+)-serine methyl ester silyl ether with NaBH4 followed by acidic workup produced the chiral serinol derivatives with minimum racemization. Addition of MeMgBr gave the functionalized amine diol in high yield with no racemization.
